An Islamic State video appears to show recruits from China’s Uighur minority threatening to “avenge oppression,” feeding into Beijing’s assertion of a growing jihadist-terror threat.

The half-hour video was released Monday by an Islamic State division in western Iraq, said the SITE Intelligence Group, which monitors online jihadist activity. Subtitled in both Arabic and Uighur, it shows what SITE says are Uighur fighters on the battlefield, as well as several grisly executions of accused informants.
